1. What is Poise to Centipoise Conversion?

The poise (P) and centipoise (cP) are units of dynamic viscosity in the centimeter-gram-second (CGS) system. 1 poise equals 100 centipoise. This conversion is commonly used in fluid mechanics and rheology.

2. How Does the Calculator Work?

The calculator uses the simple conversion formula:

Where:

• \( cP \) — Viscosity in centipoise
• \( P \) — Viscosity in poise

Explanation: The conversion is a straightforward multiplication by 100 since "centi" represents 1/100 of the base unit.

3. Importance of Viscosity Conversion

Details: Centipoise is more commonly used than poise in practical applications because it provides more convenient numbers for typical fluid viscosities (water at 20°C is about 1 cP).

4. Using the Calculator

Tips: Enter the viscosity value in poise (P). The calculator will automatically convert it to centipoise (cP). The input must be a positive number.

5. Frequently Asked Questions (FAQ)

Q1: What is the relationship between poise and centipoise?
A: 1 poise = 100 centipoise. Centipoise is 1/100th of a poise.

Q2: Why is centipoise more commonly used than poise?
A: Centipoise provides more convenient numbers for typical fluid viscosities (e.g., water at 20°C is ~1 cP rather than 0.01 P).

Q3: What is the SI unit equivalent of 1 poise?
A: 1 P = 0.1 Pa·s (pascal-second), the SI unit of dynamic viscosity.

Q4: What are typical viscosity values in centipoise?
A: Water at 20°C: ~1 cP, Olive oil: ~84 cP, Honey: ~10,000 cP, Air: ~0.018 cP.

Q5: How does temperature affect viscosity?
A: For liquids, viscosity typically decreases with increasing temperature. For gases, viscosity typically increases with temperature.
